Greetings all,
I'm trying to do a multi-line substitution of a particular sort and things
aren't quite working out. I've been grinding at it for a little bit now
to the point that I think it's time to ask for some assitance. I'm using 5.10.
Say I have the following:
my $code=<<__CODE__;
: sub hello {
: say "Hello World!";
: }
__CODE__
I would like to get back:
[code] sub hello {
say "Hello World!";
}
[/code]
I've been playing around with the zero-width lookbehind assertions, but it
seems as if the positive (?<=) and negative (?<!) behave differently. Both
are supposed to make the match, but not include it in $&. Negative works
that way, but positive is including or so it seems. Here is what I have so
far...
$code =~ s@(?:(?<=\s\:).*)+@"[code]$&[/code]"@esg; (gives me)
:[code] sub hello {
: say "Hello World!";
: }
[/code]
$code =~ s@(^(\s\:)(.*)$)+@"[code]$3[/code]"@esg; (gives me)
[code] sub hello {
: say "Hello World!";
: }
[/code]
Both are close in their own ways, but no cigar. I've tried other permutations
of the regex to no avail.
I know I could do this with two regex, but for reasons that are not pertinent
to the discusion, I would really like to do this with one.
Any hints?
thanks.
